Go to Other and check Nonmanifold Geometry and Normals and Geometry. Click on the box located on the right of the word to open the Polygon Cleanup Options dialog window. If you get a message saying Cannot Reduce Polygonal Object with Nonmanifold Geometry, go to the top menu and select Polygons > Cleanup. Keep reducing the polygon count until your tree has less than 15,000 polygons. Check the following parameters, and keep Mesh Borders, UV borders, Hard Edges. Click on the box located on the right of the word to open the Polygon Reduce Options dialog window.Įnter the percentage of reduction. Select a tree and choose Polygons > Reduce. In most cases, you will need to use the following polygon reduction to reduce the number of polygons while keeping the integrity of the 3D object. You will notice that this operation can radically alter the shape of the model. Go to the Rendering menu and select Paint Effect > Paint Effects Mesh Quality.ĭecrease the number of polygons by moving the sliders to the left for Tube Sections and Segment, and check the number of polygons on the Polygon Count. Go to Display > Heads on Display > Polygon Count. Lets control the number of polygons for the tree. To reduce the number of polygons for a tree: Select the Modeling module in the box located on the left of the Status Line. Lets see how Maya can help you reduce the polygonal count. The output from the conversion is a high-resolution model with a high polygonal count. Choose Modify > Convert > Paint Effects To Polygons. Select one of the strokes from the Outliner window or from the perspective view. To convert the 3D Paint Effect to polygonal meshes: Lets convert the Paint Effects to 3D objects made of polygonal meshes. Conversion of 3D Models to Polygonal Meshes Check the number of Faces rendered in the scene. To view the polygonal count, go to the top menu, and select Display > Head Up Display > Poly Count. The limit for the total number of polygons created inside a scene is 50,000. Once you import the trees in Virtools, you will clone them to create a whole forest. Two or three types of trees are needed for your scene in Maya. In the Attribute Editor, check Sample Density and Tube Segments, which are the main parameters. Select the brush stroke and press the Control + A keys. To tweak parameters for your brush stroke in the Attribute Editor: Lets control the creation of your vegetation by tweaking parameters inside the Attribute Editor. The density of the brush strokes needs to be kept low. Important note: Because you will convert the content from your 3D painting into polygonal meshes, you have to keep an eye on the number of polygons. Select Grass on the left side of the Visor window, and click on the icon to choose the grass of your choice. Render the scene to see the final result. Maya creates randomly generated lush trees with a realistic look. Go to the Workspace and click and drag the mouse pointer a short distance near the Origin center in the Perspective window. On the left side of the Visor window, click on the icon of the. The Paint Effects Brush Settings dialog window opens. Go to the top menu and click on Paint Effects > Template Brush Settings. You can select a variety of paint effects inspired by natural forms by clicking on the folder named trees. Multiple folders with preset brushes are available. To open the Visor window, go to the top menu and select Window > General Editor > Visor.
